In today's podcast, we review an episode of the British television series Black Mirror. Black Mirror is an anthology show that presents a dark spin on our relationship with technology. The series, despite its flaws, is highly entertaining and full of interesting thought experiments. Today we are focusing on the Christmas special, a longer episode that deals with some our favorite topics: augmented reality, privacy, and emulated brains. Although we recommend watching the episode before listening to this podcast, we do summarize the plot as we go for the benefit of people who have not yet seen Black Mirror.
